Yes, blue ticks means that message is read, but sometimes you
may have just opened up the chat by accident, or just wish to clear
the notification count. So this blue tick system may not be 100%
reliable.
This goes out to android users, I am not so sure about iOS users
though as I do not own any iOS devices.
You may wish to turn off your blue ticks, however, you will not
be able to see if other people blue ticked you. Blue ticks
CANNOT be turned off for group
conversations.
